Fit my Weber Genesis Silver B perfectly. Original grates are porcelain coated cast iron but at 20 years old, started to deteriorate. I didn't want to pay the exorbitant amount for original replacements so went with these. Definitely lighter and not cast iron, even though porcelain coated. Regardless, they fit well and get nicely hot leaving good sear marks on my steaks. I've used these over several grill events and they are holding up well. Highly recommended as an economical alternative.
